01Computer engineer, BYU '21. Currently shipping firmware for connected access-control hardware.
02I design boards, write firmware, run a mixed-arch Kubernetes cluster, and love spending time outside.
03I learn by building. Most things on this site started as 'I wonder if…' and ended on an oscilloscope at 2am.
